Abstract

L'invention concerne un nœud de réseau (100 ou 200) configuré pour déterminer, d'après un degré de congestion d'un réseau d'accès sans fil (10), une période d'expiration d'un chronomètre (101) utilisé pour déterminer une transition d'un état connecté à un état inactif d'un terminal mobile (300) qui se connecte via le réseau d'accès sans fil (10) à un réseau fédérateur mobile (20). Il est donc possible, à titre d'exemple, de supprimer la diminution du taux de succès de connexion au réseau par des terminaux mobiles qui peuvent se produire en raison d'ajustements réalisés sur la période d'expiration d'un chronomètre d'inactivité d'EU.
